ThesisItem Open Access Effect of nano-sized gypsum on growth and productivity of wheat (Triticum aestivum L.)(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-12) Rawat, Anupama; Singh, Vijay PalA field experiment entitled “Effect of nano-sized gypsum on growth and productivity of Wheat (Triticum aestivum)” was conducted at the Norman E Borlaug Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar (U.S Nagar) From November 2016 to April 2017. Surface Soil (0-15 cm) of the experiment field was silty clay loam in texture, medium in organic carbon (0.72%), low in available N (218.59 kg/ha), medium in available P (12.53 kg/ha) and medium in available K (149.56 kg/ha) with neutral soil reaction (pH 7.3). In addition to the field experiment two laboratory experiment entitled “Effect of nano-sized gypsum on germination of wheat” and “Effect of nano-sized gypsum blended MS media solution on seedling growth of wheat” was conducted simultaneously to investigate the effect of nano-sized gypsum on emergence and initial seedling growth more precisely. The field experiment was conducted in randomized block design with 3 replications while both the laboratory experiment was conducted in CRD each with 3 replications. For the experiment variety DPW 621-50 was used. The laboratory studies suggest that seed treatment with 100ppm nano-sized gypsum enhances germination and further seedling growth of wheat. In the field experiment it was found that 75% of RDF along with nano-sized gypsum and clay based nano-sized gypsum produced yield at par with 100 % RDF, thus saving 25 % of the RDF. Similarly among plant based nano-sized gypsum, Parthenium based nano-sized gypsum along with 75% of RDF gives promising results. High yield in nano-sized gypsum (4 t/ha), Parthenium based (3.73 t/ha) and clay based nano-sized gypsum (4.07 t/ha) was due to high photosynthetic surface i.e. leaf area index and high yield attributing characters. Hence, 75% of RDF along with nano-sized gypsum or clay based nano-sized gypsum can be recommended to the farmer.ThesisItem Open Access Cropping system for sustainable fodder and bioenergy production(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-11) Prajapati, Brajkishor; KewalanandA field experiment was conducted at the Sorghum Agronomy Block of Instructional Dairy Farm, Nagla of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar (U. S. Nagar), Uttarakhand, India, during 2015-16 and 2016-17. The treatments consisted of 12 fodder crop rotations (single cut sorghum+cowpea-oat+berseem-single cut sorghum+cowpea (control), sweet sorghum+rice bean-oat+berseem-sweet sorghum+cowpea, sweet sorgum+phillipesara- 6 row barley+berseem-sweet sorgum+cowpea, sweet sorghum+phillipesara- 2 row barley+berseem-sweet sorghum+ cowpea, sweet sorghum+cowpea-rye grass+berseem-sweet sorghum+cowpea, pearl millet+rice beanoat+berseem-sweet sorghum+cowpea, pearl millet+ phillipesara-6 row barley+berseemmaize+cowpea, pearl millet+cowpea-rye grass+berseem-maize+cowpea, maize+rice beanoat+berseem-maize+cowpea, -maize+phillipesara-6 row barley+berseem-maize+cowpea, maize+cowpea-rye grass+berseem-maize+cowpea, hybrid napier-hybrid-napier+berseemhybrid napier) were tested in randomized block design with three replication. Season wise total yield of intercropping system was highest due to hybrid napier, sweet sorghum+cowpea (kharif), rye grass+berseem (rabi) and in summer sweet sorghum+cowpea. Kharif season, fodder mixture from maize+cowpea intercropping system contained higher crude protein and digestible dry matter content. Other quality traits, dry matter intake (DMI), cell content, relative feed value (RFV), total digestible nutrients (TDN), net energy (NEl), metabolizable energy (ME) and mineral content was more in fodder mixture of sweet sorghum+cowpea intercropping system. Total yield of rotation viz., green fodder, dry fodder, crude protein, digestible dry matter, mineral and organic matter, cropping system productivity (q/ha/day), land use efficiency (LUE), heat energy and carbon sequestration was more in hybrid napier-hybrid-napier+berseem-hybrid napier crop sequence followed by sweet sorghum+cowpea-rye grass+berseem-sweet sorghum+cowpea crop rotation Highest biogas production was observed in the substrates of hybrid napier and pearl millet crop compared to other crop substrates. On the basis of the present investigation it is conclude that hybrid napier based crop rotation or sweet sorghum+cowpea-rye grass+berseem-sweet sorghum+cowpea cropping sequences are best to get higher yield, quality fodder and soil health.ThesisItem Open Access Weed management in direct seeded rice and Brahmi intercropping system in rotation with zero-till wheat(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Joshi, Neeshu; Pande, Sunita T.The above study was conducted at N.E.Borlaug Crop Research Centre, G.B.Pant University of Agriculture and Technology, Pantnagar (Uttrakhand) during two consecutive years (2015-16 and 201617). The experiment was set out in randomized block design with three replications. Total ten treatments allocated to direct seeded rice and brahmi intercropping were (1) 1:1 pendimethalin as pre-emergence (2) 1:1 pendimethalin fb twice hand weeding at 30 and 45 DAS/DAP (3) 1:1 pendimethalin fb cyhalofopbutyl supplemented with hand weeding at 45 DAS/DAP (4) 1:1 weedy check (5) 2:1 pendimethalin as pre-emergence (6) 2:1 pendimethalin fb twice hand weeding at 30 and 45 DAS/DAP (7) 2:1 pendimethalin fb cyhalofop-butyl supplemented with hand weeding at 45 DAS/DAP (8) 2:1 weedy check (9) sole rice (10) sole brahmi. Results revealed that among various treatments, paired series (2:1) of direct seeded rice and brahmi along with pendimethalin as pre emergence fb cyhalofop-butyl as post emergence fb one hand weeding at 45 DAS was found superior in terms of reduction in total weed density and dry matter accumulation of weeds and also higher WCE. Sole rice (pendimethalin fb cyhalofop-butyl fb hand weeding at 45 DAS/DAP) recorded highest value for growth parameters, yield attributes, grain yield (5.30 and 6.56 t/ha in 2015-16 and 2016-17) followed by paired ratio (2:1) along with pre and post-emergence herbicide supplemented with hand weeding at 45 DAS (4.81 and 5.75 t/ha in 2015-16 and 2016-17) over all the treatments. Sole brahmi (3 hand weeding at 30,45 and 60 DAP) recorded maximum dry herbage yield (2.07 and 2.35 t/ha in 2015-16 and 2016-17, respectively) followed by alternate row (1:1) ratio along with pendimethalin as pre emergence fb cyhalofop-butyl as post emergence supplemented with one hand weeding at 45 DAP (2.00 and 2.12 t/ha in 2015-16 and 2016-17, respectively). Maximum value of intercropping parameters viz., LER, ATER, RCC, Aggressivity, RYT and competition ratio were recorded in paired (2:1) ratio along with sequential application of pendimethalin as pre fb cyhalofop-butyl as post supplemented with one hand weeding at 45 DAS/DAP. Significantly higher value of soil N, P, K content and enzyme activity (viz., urease, dehydrogenase, acid phosphatase and alkaline phosphatase) were recorded in sole brahmi (3 hand weeding at 30,45 and 60 DAP) during both the years. The higher benefit cost ratio (9.41 and 11.07 in 2015-16 and 2016-17, respectively) were registered in alternate (1:1) ratio along with sequential application of pendimethalin fb cyhalofop-butyl fb one hand weeding at 45 DAS/DAP. Significant differences were observed in total weed density and dry weight and WCE in succeeding zero-till wheat which were treated by various combination of herbicides during previous year in rice+brahmi intercropping treatments. Highest WCE was recorded in sole brahmi (3 hand weeding at 30,45 and 60 DAP) which was significantly superior than other treatments during both the years. Highest value of yield attributes and grain yield (5.20 and 5.50 t/ha in 2015-16 and 2016-17, respectively) of wheat was recorded in sole wheat which was at par with both row ratios along with sequential application of pendimethalin fb cyhalofop-butyl fb hand weeding at 45 DAS while brahmi dry herbage yield (1.87 and 1.80 t/ha in 2015-16 and 2016-17, respectively) was significantly superior than other treatments during both the years. Higher benefit cost ratio in succeeding zero-till wheat was found in alternate ratio of 1:1 (8.46 and 8.76 in 2015-16 and 2016-17,respectively) as compared to 2:1 series of rice and brahmi and sole crop of rice and brahmi.ThesisItem Open Access Studies on crop intensification and establishment techniques in rice-wheat cropping system under irrigated condition(G.B.
